kernel/range: Uplevel the cxl subsystem's range_contains() helper
In support of the CXL subsystem's use of 'struct range' to track decode address ranges, add a common range_contains() implementation with identical semantics as resource_contains(); The existing 'range_contains()' in lib/stackinit_kunit.c is namespaced with a 'stackinit_' prefix.
